                                <h3>题目描述</h3><p><div>A very important and complicated machine consists of n wheels, numbered l, 2, . . . , n. They&nbsp;</div>
<div>are actually cogwheels, but the cogs are so small that we can model them as circles on the plane.&nbsp;</div>
<div>Every wheel can spin around its center.&nbsp;</div>
<div>Two wheels cannot overlap (they do not have common interior points), but they can touch.&nbsp;</div>
<div>If two wheels touch each other and one of them rotates, the other one spins as well, as their&nbsp;</div>
<div>micro-cogs are locked together.&nbsp;</div>
<div>A force is put to wheel I (and to no other wheel), making it rotate at the rate of exactly&nbsp;</div>
<div>one turn per minute, clockwise. Compute the rates of other wheels7 movement. You mav assume&nbsp;</div>
<div>that the machine is not jammed (the movement is physically possible).&nbsp;</div>
<div>
<div>给出平面上的n个齿轮，忽略齿的大小。它们不能有交集，但可以相切。当用T=1的速度推动1号齿轮时（相切的转动，可以传动），求每个齿轮的转速。你可以假定机器不会卡死。&nbsp;</div>
<div>n&lt;=1000&nbsp;</div>
<div>其余数字&lt;=10000&nbsp;</div>
<div></div>
</div>
<div></div>
<p></p></p><hr/><h3>输入格式</h3><p><div>The first line of input contains the number of test cases T. The descriptions of the test cases&nbsp;</div>
<div>follow:&nbsp;</div>
<div>Each test case consists of one line containing the number of wheels n (1《 n&le; 1000) . Each&nbsp;</div>
<div>of the following lines contain three integers x, y and r (-10 000 &lt; x, y &lt; 10 000; I&le; r&le; 10 000)&nbsp;</div>
<div>where (x, y) denote the Cartesian coordinates of the wheel's center and r is its radius.&nbsp;</div>
<div></div>
<p></p></p><hr/><h3>输出格式</h3><p><div>For each test case, output n lines, each describing the movement of one wheel, in the same&nbsp;</div>
<div>
<div>order as in the input. For every wheel, output either p/q clockwise or p/q counterclockwise,&nbsp;</div>
<div>where the irreducible fraction p/q is the number of wheel turns per minute. If q is l, output just&nbsp;</div>
<div>p as an integer. If a wheel is standing still, output not moving.&nbsp;</div>
